You have realize that airbrush colours no matter what type are extremely thin but very opaque I use them for washes. Personally Vajello are extremly good for airbrushes as they are very thin and smooth and are very opaque.

I use both types of paint in my brush and haven't had alot of trouble out of either one. I did learn early on that Citadels need alot of Flo-Aid to get them thin enough but they dry up fine and look good.

Ah, you have chosen a topic near and dear to me - my everfaithful airbrush.

First off, I can vouch that citadel paint can be fired thru an airbrush (albeit very thinned), I do it regualrly. What you need to look for in an airbrush for modeling purposes is a good single action heavy-weight brush. I personally use a Pasche F1 for things like blends on outstretched swords and an H series for vehicles. These are my work-horses. Both of these are bottom fed, single action (push the button and paint) and have a hella wide flow from the cup to the tip which makes of easy clean-up and a minimum of clogs. Good for beginers and inexpensive too (my F1 cost $29!)

I also own 2, double action side feed guns for my illustration work and would never entertain the idea of using them for model work as their parts are much too fine for heavy viscosity paints. I mostly use inks and gouches in these.

The single most important piece of equipment is a good air compressor. You need at least a 4 gallon tank that can shoot a minimum of 60 psi and prefferably as high as 120 psi. Most beginners get frustrated with the grainy efect that cheap "airbrush" pumps cause. A high pressure spray makes for a much smoother effect overall. I have an 8 gallon compressor I bought from Sears. It has good capacity and delivers a good constant 60-80 psi flow. It ran me about $250 (I do use it for other things too), but a small 2-4 gallon compressor will cost $85-$125.

Eld I almost agree 100% exceptfor the single action... I use dual action on all my models, not just my larger ones. Never had problems either.. sure it takes alot more to be able to use a dual on models, but then again, after doing technical for 7 years I would never use a single action for anything but basecoats.

Compressor is very important as mentioned above, also keep in mind you MUST have a moisture trap and a good regulator.

McCOPPEL: For my Illustration work I use a Badger and a Thayer Chandler double action guns. Even with a flow aid thinner I'd be sketchy about shooting Citadel paints thru those. GW paint in general dries really "plastic" and I'd be cleaning my real expensive dual actions more than I'd be painting My big Pasches work much better for models, eaiser to clean and the nozzles practically work like a dual action anyway.

I use a Paasche H type, syphon fed external mix for base coat work. Works pretty well I must say. I do have a question though, what is the difference between the external mix Paasche's and the internal mix Paasche's?
